Viper's bugloss - a heavenly blue

Little to report photographically today until I found this beautiful blue flower, a viper's bugloss, in Stirling's King's Park while walking the dog tonight. This has grown from a seed that failed to germinate last year after planting by Stirling's On The Verge project, which is creating flower-rich patches for bees all across Stirling and beyond. I like to think that this delayed germination is gratification deferred!
